What Is a 20 lb Propane Tank
A 20 lb propane tank is a portable steel cylinder that holds approximately 4.7 gallons of liquid propane (the "20 lb" refers to the weight of the propane it carries, not the tank itself). It is the standard size cylinder used for residential BBQ grills, portable heaters, camping equipment, and many other consumer applications. The cylinder has an OPD (Overfilling Prevention Device) valve and must be certified every 12 years for safe use.
In Puerto Rico, the 20 lb cylinder is the most common propane tank in homes across the island.
What Can You Use a 20 lb Propane Tank For
The 20 lb propane tank powers a wide range of applications: residential gas grills and BBQs, patio heaters and outdoor fire pits, mosquito traps and outdoor pest control, portable propane heaters for garages and workshops, small portable generators for emergency backup, food trucks and outdoor cooking equipment, camping stoves and lanterns, and propane-powered tools.
For most families in Puerto Rico, the 20 lb tank is the everyday propane workhorse.
How Long Does a 20 lb Propane Tank Last
How long a 20 lb tank lasts depends on what you are running and how often. A typical residential BBQ grill burning at moderate heat uses about 1 to 2 lbs of propane per hour, meaning a full 20 lb tank lasts approximately 10 to 20 hours of grilling. A patio heater consumes more, typically 2 to 3 lbs per hour, so a tank lasts roughly 7 to 10 hours.
Track your usage and refill before running out completely to avoid air contamination in the cylinder.

Refill vs Exchange for 20 lb Tanks
You have two options for getting a refilled 20 lb cylinder in Puerto Rico. Refill means we put propane in your existing cylinder. Exchange means we swap your empty cylinder for a pre-filled certified one at the location.
Refill typically costs less per gallon because you only pay for the propane, not a swap fee. Exchange is faster because there is no waiting for the refill. If your cylinder is expired or damaged, exchange may be the only option. Call 787-641-8002 to find what is available at the nearest plant.
20 lb Propane Tank Certification and Safety
Every 20 lb propane cylinder must be certified safe to use. Federal regulations require certification when the cylinder is first manufactured and re-certification every 12 years thereafter. The certification date is stamped on the cylinder collar.
If your cylinder is past its certification date, Tropigas cannot legally refill it. We can exchange it for a certified cylinder, or you can have it re-qualified by a certified facility. Call 787-641-8002 for certification questions.
How Much Does a 20 lb Propane Refill Cost in Puerto Rico
The cost to refill a 20 lb propane cylinder in Puerto Rico depends on current propane prices and the plant location. Refill is priced per gallon of propane added. Typically, a full 20 lb refill costs significantly less than buying a new pre-filled cylinder at retail.
For current 20 lb refill pricing in your area, call 787-641-8002 or visit the nearest plant.
